In an automatic lathe having a work spindle and one or more reciprocatable tool slides, each slide is connected to fluid-operated means actuated via a transmission by a control cam. Radial tool slides 20 are mounted on a machine member 54 by an arm 56 and the axial tool slides 22 and 24 are attached to means 28 pivotably mounted on a guide block 30 by shaft 32. The tool slides 20 are hydraulically actuated assemblies the piston 102 of each having forwardly and rearwardly extending portions 104 and 106 respectively, for mounting a tool holder 108 and a guide plate 110 which has adjustable stops 112 and 114. Attached to the guide plate is a cam member 118 which cooperates with the piston of hydraulic unit 120 which controls the rapid advance movements of the tool slide. The lathe control system 70 includes a cam 76 for each slide mounted on a shaft 74, each cam co-operating with a lever 84 having an adjustable pivot 90.

Abstract: 1434110 Railway vehicle undercarriages AVON RUBBER CO Ltd 22 Aug 1973 39883/73 Heading B7L [Also in Division F2] The railway vehicle resilient side bearer of Specification 1,373,083 (i.e. a hollow elastomeric tube 60 secured between two elongate plates 62, 66) is provided with means 63, 64, 74, 75 which, whilst allowing relative movement of the plates 62, 66 towards each other, resists their relative movement parallel to each other. Thus radial compression of the tube 60 is allowed, whereas longitudinal and rolling shear are resisted. Midway along their length, one plate 62 is provided with a sleeve 63 and the other plate 66 with a spigot 64, the sleeve and spigot being housed in a transverse hole in the tube 60. A bushing consisting of an elastomeric bush 75 and a sleeve 74 is force-fitted into the annular space between the sleeve 63 and the spigot 64. On movement of the plates 62, 66 towards each other, the spigot 64 and the sleeve 74 slide over each other without stressing the bush 75. However on subsequent side-to-side or front-to-back movement of the plates the spigot 64 moves radially relative to the sleeve 63, placing the bush 75 in radial compression. The bogie (not shown) is mounted on the bearer via a friction pad 68.

A concrete cell enclosing a radioactive device, is provided with service lines connecting the device to a control panel in an inhabitable compartment of the cell. The service lines pass through a channel in a wall which serves as a radiation shield. The channel is formed in the base of an aperture in the wall, the aperture itself being closed by a removable plug. When the radioactive device is to be removed from the cell, the service lines are uncoupled from the control panel within the inhabitable compartment, the plug is lifted from the aperture and the device and attached lines are lifted from the cell. The plug may be moved vertically into engagement with a U-shaped aperture, i.e. one which is open at the upper surface of the wall, or it may be lowered on to inclined guide rails which permit the plug to slide laterally into the aperture, formed as a hole through the wall.

Abstract: 1,274,267. Rotary conveyers for ferrite cores and semi-conductors. INTERNATIONAL BUSINESS MACHINES CORP. 13 Aug., 1969, No. 40474/69. Heading B8A. [Also in Division H1] Ferrite cores, semi-conductor chips &c. are fed by a vibrating feed bowl 50 to a pickup station 320 where they are received in the suction pockets of a rotor 80, each pocket repeatedly engaging the cores as it is indexed to the station so that all pockets are filled, each with a single respective core, the cores then being transported by the rotor to a testing station. Each pocket is defined by a radial passage defined (as shown most clearly in Figs. 4, 5 and 7) by respective radial slots 232 in an annular plate 196. These are covered on the upper side of the plate 196 by an unslotted annular plate 200, and on its under-side by an annular plate 194. The latter is formed with the slot-like recesses 220 which register with the slots 232 but do not open into the periphery of the plate 194. They open into the centre 214 which connects with a source of vacuum. Thus a single core only, can be retained at the periphery of each slot 232 (Figs. 4 and 5). As the cores are carried round by the rotor 80, a probe 281 respective to each slot 232, is lowered by the action of a cam 78. The latter acts on heads 294, each carried by a member 282 carrying a respective probe 281 and normally upwardly biased by a spring 298. The probe enters the interior of the annular core and reacts with contacts 344, 346, 348 and 350 (Fig. 5) thereby testing the core in a desired manner. The cores are then successively discharged, as the rotor 80 proceeds, either into a conduit 102 if the result of the test is satisfactory, or otherwise into a conduit 96. The conduit 102 leads into a container (90), (Fig. 6, not shown).

Patent GB-415621-A (GB)
Abstract: 415,621. Air - heating and cooking stoves. TENNANT, W. J., 111, Hatton Garden, London.-(Jeddo-Highland Coal Co. ; Jeddo, Pennsylvania, U.S.A.) Dec. 1, 1933, No. 33810. [Class 126.] A combined air-heating and cooking stove comprises two combustion chambers 35, 36 within a casing 10, a common discharge port 12 for the combustion products of both chambers, and means for leading the combustion products from either chamber directly to the discharge port, or indirectly thereto, through a heat-exchanger for heating air, as desired. The chambers 35, 36 are placed side by side, together with an oven 45. At the rear of the stove is an air-space 44, with inlet and outlet openings 23, 24. Air is supplied by a fan through the opening 23. Situated in the airspace 44 is a heat-exchanger comprising two chambers 50, 51 for the passage of combustion products. The chambers 50, 51 are connected together at one end by a flue 52. The chamber 50 communicates with the outlet port or chimney opening 12. Flues from the combustion chambers 35, 36 pass rearwardly and are controlled by dampers 61, 65 and communicate under the control of further dampers with the part 12 either directly or indirectly through the heat-exchanger chambers 50, 51. The combustion chamber 36 also communicates laterally, under the control of a valve 55, with the flue 56 passing around the oven 45 and leading at 54 to the flue 52. A baffle 57 is provided in the flue 56. Thus, under the control of the valves, the air supply or the oven, or both, may be heated as desired. The chamber 44 communicates with the space 37 between the combustion chambers 35, 36 and the space 38 between the chamber 35 and the outer wall. Hoods 42, 43 deflect air from the opening 23 into these spaces 37, 38. Apertures 75, 76 controlled by dampers 77, allow air to pass from the space 37 into the combustion chambers 35, 36. An intermediate wall 41 in the space 38 reduces loss of heat. The side and front walls and part of the top of the stove are lagged with asbestos or other material. A port with a cover 92 is provided in the top of the stove, and, when natural draught is used for the air supply, is opened, and the port 24 is closed. The dampers such as 61, 65 are operated by arms 61<1>, 65<1> passing through the top of the stove. A boiler 68 is provided at the rear of the combustion chamber 36. In the air chamber 44 is provided a humidifier comprising a tank 86 fed from the inlet pipe of the boiler 68, and provided with a wick 90. The air supplied to and heated in the stove passes through the outlet port 24 into a hot air distributing main, and is delivered through a number of registers in the rooms to be heated.
